53 million Americans made purchases on the day, but traffic to eBay, Macy's and Walmart also jumped on the day. What's more interesting for us is the impact it has on third party businesses selling on Amazon Marketplace - our data suggests that those who sell Electronics and Tech goods benefited the most with a 50% increase in revenue.

While it has some limitations (only items in the eBay Deals selection qualify, and it won’t match against 3rd party sellers on other marketplaces, only Walmart/Amazon/Jet first-party offerings), it’s a welcome move for both customers and the retailers participating in eBay Deals offers.

Unsurprisingly many felt they hadn’t had adequate warning, resulting in a storm of backlash.

That doesn’t have to be an Amazon own brand, but it does give Amazon a huge level of control over potentially hugely valuable search result real estate.
